MORE NEW GEOTECHNICAL STANDARDS

The BSI have announced changes to a number of geotechnical engineering related standards in recent months. Though by no means exhaustive the list of changes affecting this sector includes:

  • BS 8002:2015 Code of practice for earth retaining structures.
  • BS 8004:2015 Code of practice for foundations.
  • BS 5930:2015 Code of practice for ground investigations.
  • BS 8081:2015 Code of practice for grouted anchors.
  • BS EN 1536:2010 Amendment 1, Execution of special geotechnical work. Bored piles.
  • BS EN 1538:2010 Amendment 1, Execution of special geotechnical work. Diaphragm walls.
  • BS EN 1992-1-1:2004 Amendment 1, Eurocode 2. Design of concrete structures.
  • BS EN 1993-1-1:2005 Amendment 1, Eurocode 3. Design of steel structures.
  • BS EN ISO 17628:2015 Geotechnical investigation and testing. Geothermal testing.
  • BS EN ISO 25619-2:2015 Geosynthetics. Determination of compression behaviour.

NEW STANDARDS FOR GEOTECHNICAL AND STRUCTURAL ENGINEERS

Important updates to British Standards commonly used by geotechnical and structural engineers have been published:

  • BS 8002: 2015 Code of practice for earth retaining structures. This revised and updated standard conforms to the latest EN and EN ISO standards and provides recommendations for the design, construction, monitoring, and maintenance of earth retaining structures. It provides additional information to the recommendations in EC7 for surcharges, unplanned excavations and prop loads, and provides detailed recommendations for the content of Geotechnical Feedback Reports in accordance with EC7.
  • BS 8004: Code of practice for foundations. Providing recommendations for the design of both shallow and deep foundations to meet the latest EN and EN ISO standards, the new standard provides additional information to EC7 recommendations for spread foundations, provides recommendations for the design of piles that reflect modern practice, and and provides detailed recommendations for the content of Geotechnical Feedback Reports.

All related courses offered in 2016 by our sister company Surepath Training will make reference to the new standards and provide guidance on their use in practice. Please contact us for the details of the revised course details.

COLSTERWORTH CULVERTS

Surepath Consulting recently completed a commission in Colsterworth, Lincolnshire, where a planned highway improvement had identified the need to appraise the stability of an existing road embankment over a culvert. Geo Matters Limited  were retained by their client to undertake the ground investigation and the stability appraisal, but due to the specialist nature of the latter (including  traffic impact loads and vegetation effects). Surepath were retained to support Geo Matters to undertake the stability analyses and prepare a Geotechnical Design Report in accordance with EC7. The aim of the work is ultimately to secure adoption of the highway.
